Product Overview

Product Description

SD Series API BB3 Pump – Axially Split Casing for Easy Rotor Access

Axially split casing allows removal of top half without disturbing piping or alignment – simplifies maintenance. Opposed impeller arrangement balances axial thrust hydraulically. Heavy-duty bearings with forced oil lubrication handle high radial loads. Wide material selection for sour service, high chloride, or high-temperature hydrogen environments. API 610 11th edition compliant.

KEY FEATURES

  • API 610 BB3 Compliance: Fully compliant with 11th edition API 610 – axially split, multistage, between-bearing design for high-pressure hydrocarbon service.
  • Ultra-High Pressure Capability: Maximum working pressure up to 25MPa (250 bar / 3625 psi), suitable for the most demanding pipeline and boiler feed applications.
  • Axially Split Casing: Top half casing removes easily, providing full access to rotor components without disturbing piping or driver alignment – reduces maintenance time by up to 50%.
  • Hydraulically Balanced Rotor: Opposed impeller arrangement cancels axial thrust without complex thrust bearings, improving reliability.
  • Wide Temperature & Material Range: Handles -80°C cryogenic to +210°C high-temperature media; materials from carbon steel to duplex, high-temp alloy, and lined options.

Frequently Asked Questions

What is the maximum head and pressure the SD series can achieve?
The SD series delivers a maximum head of 2000 meters and a maximum working pressure of 25MPa (250 bar). This makes it suitable for long-distance crude oil pipelines (boosting every 50-100km) and high-pressure boiler feed in supercritical power plants.
How is axial thrust managed in this multistage pump?
The SD series uses an opposed impeller arrangement (impellers mounted back‑to‑back in pairs). This design hydraulically balances axial thrust without requiring a large thrust bearing – only a small balance device is needed for residual thrust. This greatly improves reliability and extends maintenance intervals.
What materials are available for sour crude or high‑chloride service?
For sour crude containing H₂S, we recommend carbon steel with NACE MR0175 compliance (sour service). For high‑chloride environments (e.g., seawater injection), duplex or super duplex stainless steel (2205/2507) is available. Our engineering team will select the optimal material based on your fluid composition, temperature, and pressure.
The pump is rated for high voltage (6kV/10kV). Do you provide complete motor control and skid packages?
Yes. We can supply the SD series pump as part of a complete engineered skid package including: high‑voltage motor (6kV or 10kV), variable frequency drive (optional), control panel with soft starter, instrumentation, and all interconnecting piping. For pipeline projects, we also provide pigging compatibility and remote monitoring systems. Please provide your project specifications for a custom proposal.
